(54) СПОСОБ ГИДРОАБРАЗИВНОЙ ОБРАБОТКИ ПОВЕРХНОСТЕЙ ИЗДЕЛИЙ(54) METHOD OF HYDROABRASIVE TREATMENT OF PRODUCT SURFACES

II

Изобретение относитс  к гидроабразивной обработке поверхностей изделий.The invention relates to water-jet surface treatment of products.

Известны способы гидроабразивной обработки поверхностей изделий, при которых гидроабразивную суспензию под давлением подают на обрабатываемую поверхность 1.Known methods of hydroabrasive surface treatment of products in which the hydroabrasive suspension under pressure serves on the treated surface 1.

Недостаток известного способа заключаетс  в окислении обрабатываемых деталей .The disadvantage of this method is the oxidation of the workpiece.

Цель изобретени  - снижение скорости окислительных реакций.The purpose of the invention is to reduce the rate of oxidation reactions.

Указанна  цель достигаетс  тем, что гидроабразивную суспензию дополнительно насыщают нейтральным газом.This goal is achieved in that the hydroabrasive slurry is additionally saturated with a neutral gas.

Предлагаемый способ осуществл ют следующим образом.The proposed method is carried out as follows.

Поток суспензии, разгон емый давлением от насосной системы, подают на обрабатываемую поверхность, дополнительно насыща  его газом, например, углекислотой , азотом,, их смесью и другими. Насыщение газом производ т непрерывно, со скоростью , пропорциональной давлению и ско-. рости подаваемого потока суспензии. Подача суспензии на обрабатываемую поверхность , насыщение ее газом, режимы обработки , обрабатываемый материал - все может быть различным, иметь различные варианты. Так, поток суспензии может быть направлен на деталь а виде струи, деталь может находитьс  полностью или часJ тично внутри потока, быть погруженной в емкость с перемещиваемой суспензией, и др. т. п.The suspension stream, accelerated by pressure from the pumping system, is fed to the surface to be treated, additionally filling it with gas, for example, carbon dioxide, nitrogen, their mixture and others. The saturation with gas is carried out continuously, at a rate proportional to pressure and speed. increase the flow of the suspension. The supply of the suspension to the surface to be treated, its saturation with gas, the processing modes, the material being processed can all be different, have different options. Thus, the flow of the suspension can be directed to the part in the form of a jet, the part can be completely or partially inside the flow, be immersed in a container with a movable suspension, etc.

Насыщение потока, подаваемого на обрабатываемую поверхность, может производитьс  различными методами и в различных точках системы циркул ции потока, - в струйном аппарате в период разгона потока , в момент подачи при выходе его из сопла - насадка, в баке и др. Насыщение газом потока также может иметь различные варианты. В поток может вводитьс  угле5 кислота и в виде мернодисперсного сухого льда, поток может газироватьс  также сжиженным или сжатым газом или их смесью, ввод  их в поток под давлением на различных этапах его движени- .The flow supplied to the surface to be treated can be saturated by various methods and at various points of the flow system, in the jet device during the flow acceleration, at the time of its delivery from the nozzle, the nozzle, in the tank, etc. may have different options. Carbon5 acid can be introduced into the stream and in the form of dry-dispersed dry ice, the stream can also be carbonated with liquefied or compressed gas or their mixture, and introduced into the stream under pressure at various stages of its movement.
